Scientists from Nanchang University found that drinking coffee reduces the risk of migraines, but not other neurological diseases. The study was published on: European Journal of Clinical Nutrition.
The study authors evaluated the existence of a link between mutations (single nucleotide polymorphisms) that increase a person’s tendency to drink coffee and various neurological diseases. This approach is called Mendelian randomization, considering only genetic data allows scientists to exclude the influence of environmental factors (other diseases, financial situation, etc.).
Scientists identified 40 mutations significantly associated with coffee consumption. It turns out that the presence of such mutations significantly reduces the risk of migraines, but does not affect the risk of other neurological diseases: Parkinson’s disease, Alzheimer’s disease and multiple sclerosis.
While the results are intriguing, the researchers highlight some limitations. Among these is the origin of the patients: most were European. Additionally, the researchers did not assess the participants’ actual coffee consumption.
